Data breaches can happen to anyone, but what the original comment implies is that Google would compromise your security, or at least your privacy, for profit. Its main profit venue is tracking people and selling ads.

Is that a breach? As far as I know, the description of that is "a google-internal audit found that some information was accessible but shouldn't have been, and found no evidence that that was accessed or used by anyone".

"Breach" usually implies actual misuse or access.
